Large Wren Birdhouse Plans

Build a simple, bird-friendly nesting box with these wren birdhouse plans, designed for creating a functional wooden birdhouse for wrens and other small cavity-nesting birds.

This design focuses on the details that matter most in a practical nesting box: a properly sized 1 1/8″ entrance hole, side ventilation holes, bottom drainage holes, an overhanging roof, and a clean box-style shape that is easy to build from standard cedar board. The plan also includes a 3″ x 3″ metal entrance hole guard, helping protect the opening from damage and making the birdhouse more durable over time.

The birdhouse is intentionally designed without an exterior perch. Native cavity-nesting birds do not need a perch, and leaving it out helps reduce access for predators or unwanted birds. Inside the front panel, the plan includes small grooves to help young birds climb out when they are ready to leave the nest.

The design uses 1×6 cedar board and #8 stainless steel screws, with clear dimensions, cutting details, and step-by-step illustrations to make the project approachable for DIY builders, gardeners, bird lovers, and anyone looking to add a useful nesting box to a backyard or garden.

This project is a strong fit for a DIY wren house, a cedar birdhouse, a backyard nesting box, or a garden birdhouse.
